THE REASON FOR THE SEARCH

Denver Glass Interiors needed to appoint a new GM into IllumiNation Window & Doors. 

The business had moved from profitability into a distressed position, with current EBITDA at -$420k (approximately -$900k total EBITDA impact). Revenue was running at ~$530k/month (sub-$7M run-rate), and operational execution was inconsistent—jobs were not completing to 100%, accountability was unclear, and service standards had slipped.

Compounding this, the business had suffered a marketing shock after a website change eliminated much of its organic SEO and showroom traffic. With supply chain lead times of 4–8 weeks and a premium customer base that expects “white-glove” delivery, the business required a GM who could rebuild execution discipline while partnering on a smarter go-to-market engine.
